During the last week Chandra completed the observing schedule as
planned.

A flight software patch was uplinked on Sep 19 that disables the
capability for the MUPS-B2 thruster firing, to prevent the risk of a
stuck open thruster. Real-time procedures were executed on Sep 19 and
20 to dump OBC-A memory as a follow-up to the patches. The dump will
be used to update the baseline memory image maintained on the ground.

A real-time procedure was used to monitor the momentum unload that was
executed from the on-board command loads on Sep 17; the unload
performance was nominal.

A Chandra image release was issued on Sep 19 describing observations
of the Coma cluster of galaxies. Galaxies clusters are the largest
structures in the Universe held together by gravity. Long arms of hot
gas been discovered in the Coma cluster of galaxies; these arms span
at least a half a million light years. These arms were likely formed
by hot gas being stripped and left behind smaller clusters of galaxies
as they merged with Coma. For details see:

The schedule of targets for the next week is shown below and includes
observations of SDSS J0908+4441 and SDSS J2222-0946 coordinated with
the Hobby-Eberly Telescope.
